The release migration is altering the database structure and requires the database user to have the DDL privileges fore creating, altering and deleting database its own objects.

Please refer to Installing a Database section for the requires privileges for each the database vendor. 

# sudo groupadd udmg

# sudo useradd -g udmg udmg

The lines starting with a semicolon ';' or a hash '#' are comments, either describing the option or showing the default value.

The parameters must be adapted to your environment, in particular:

• "paths" section: GatewayHome
• "log" section: LogLevel, LogTo, LogPath
• "admin" section: Host, Port
• "database" section: Type, Address, Name, User, Password

About the log section:

• The DEBUG and TRACE log levels are not recommended for production environments.
• The detailed log feature (distinct log file for each transfer) is disabled when the log level is set to ERROR or CRITICAL.

About the global section: the requested OS file and directory creation permissions are applied after the umask of the OS user that is running the UDMG Server process.

# Universal Data Mover Gateway Server Configuration File
#
# This configuration file specifies global options for the
# udmg-server program.
#
# The configuration file is organized with the grouping of options under
# different section that are marked by brackets: [section_name]
# This organization should be maintained when modifying the file.
#
# The file syntax is:
#
# - Lines starting with a # or a ; are comments.
# - Blank lines are ignored.
# - Option lines are 'keyword = value' format.
# - keywords are not case sensitive.
# - keywords can start in any column.
# - Case sensitivity of the value depends on the value being specified.
# For example, a yes or no option is not case sensitive, but a file
# or directory name is.
# - Values must be enclosed in quotations marks (") or apostrophes (')
# if the value contains a space or tab.
# - File or folder path on Windows platform must be written with one of the following syntaxes:
# LogPath = "C:/UDMG/UDMG Server/logs"
# LogPath = "C://UDMG//UDMG Server//logs"
# LogPath = "C:\\UDMG\\UDMG Server\\logs"
# LogPath = C:\UDMG\UDMG Server\logs
# LogPath = C:/UDMG/UDMG Server/logs

The AESPassphrase file is generated on the first run if it does not exist. It is recommended to set an absolute path, otherwise it is created in the current directory.

Make sure to verify the file location during an upgrade and to have a backup.

Without the correct AESPassphrase file, the passwords, keys, and certificates are not usable.
The use of an incorrect passphrase file is reported with the error:

cannot decrypt password: cipher: message authentication failed
